A figure cut or engraved on metal or stone, under the influence of certain planets. In order to free any place of vermin, the figure of the obnoxious animal is made in wax or consecrated metal, in a planetary hour, and this is called the talisman. (Warburton.)
He swore that you had robbed his house, And stole his talismanic louse.
S.Butler; Hudibras. part iii. 1.
The Abraxas Stone is a most noted talisman. (See
Abraxas.) In Arabia a talisman is still used, consisting of a piece of paper, on which are written the names of the Seven Sleepers and their dog, to protect a house from ghosts and demons. The talisman is supposed to be sympathetic, and to receive an influence from the planets, which it communicates to the wearer.
